## Member Typedef Documentation

## ◆ loader_fcn_t

typedef std::function<bool(const image_loader_args_t&)> uhd::image_loader::loader_fcn_t

Signature of an image loading function.

This is the function signature for an image loading function. See the declaration of load() for the meaning of these arguments.

This function must return true upon the end of a successful image load or false if no applicable device was found. It may only throw a runtime error under one of three conditions:

- The function finds multiple devices that fit the user's arguments.
- The function has already engaged with a specific device and something goes wrong.
- The user gives arguments that unambiguously lead to a specific device and expect the default image(s) to be loaded, but the specific model of the device cannot be determined beyond a category.

## Member Function Documentation

## ◆ get_recovery_instructions()

std::string uhd::image_loader::get_recovery_instructions | ( | const std::string & | device_type | ) |
| static

Get the instructions on how to recovery a particular device.

These instructions should be queried if the user interrupts an image loading session, as this will likely leave the device in an unstable state.

Parameters

  device_type | the "type=foo" value given in an –args option

Returns
  recovery instructions

## ◆ load()

bool uhd::image_loader::load | ( | const image_loader_args_t & | image_loader_args | ) |
| static

Load firmware and/or FPGA onto a device.

Parameters

  image_loader_args | arguments to pass into image loading function

## ◆ register_image_loader()

void uhd::image_loader::register_image_loader | ( | const std::string & | device_type,
|  | const loader_fcn_t & | loader_fcn,
|  | const std::string & | recovery_instructions )
| static

Register an image loader.

Parameters

  device_type | the "type=foo" value given in an –args option
  loader_fcn | the loader function for the given device
  recovery_instructions | instructions on how to restore a device
